thermostatie radiator valve constructed for the manual and thermostaticcontrol ofthe flow of heating medium therethrough, 4the valvecomprisinga casing 5 having a side?- outletnipple 6 to which a connector7 is at- '55 tached by the nut `8, the connector 7 being adapted forattachment to a radiator or other heating element. The lower' open endof the valve casing 5 has a litting 9 engaged there-5,- with as by athreaded connection and the "60 fitting 9 is adapted'to beplaced intocommunication with the source of supply of a heating medium. Atransverse web 10 is arranged interiorly of the valve lcasing 5 andforms an integral part'of the wall structure 65 This invention relatesto certain new and useful improvements in automatic thermostaticradiator valves. Y

Thesprimary object of the invention is to 5 provide an automaticthermostatic radiator valve wherein a valve casing contains a valve seatwith a manually operable valve engageable with one side thereof and athermostatically operated valve engageable with the other 10 side of thevalve casing, may be controlled either manually or thermostatically. Y Y

A further object of the invention is to provide a radiator valve of thevforegoing' character wherein a ring or annulus forming a part of thevalve casing and constructed to contain an expansible fluid, has anexpansible tube in communication therewith and directly engaged with thethermostatically operative valve to effect automatic operation of saidgo valve in controlling the opening and closing movements thereof, theexpansible fluid being rendered more sensitive by the provision of atubular cross arm extending between opposite sides of the ring orannulus and located in the valve casing in the path of iow of theheating medium.

With the above and other objects in view that will become apparent asthe nature of 3 the invention is better understood, the same consists ofthe novel construction, combination and arrangements of parts to behereinafter more fully described and then claimed.

in the accompanying drawing, forming a part of the application and towhich reference parts throughout the several 40 view of an automaticthermostatic radiator valve constructed 1n accordance with the presentinvention, and showing the manual and thermostatically operated valvesseparately engageable with opposite sides of a. valve seat, and

Figure 2 is a cross sectional view taken on lines 2-2 of Figure 1,showing the thermostatic ring or annulus and the tubular connecting webtraversing the valve casing.

Referring more in detail to the accompanying drawing, there isillustrated an automatic is had by like characters designatingcorrethereof vand is disposed below, the outlet 6a through the nipple 6,the web having a centraiI opening therein defining a valve passage withan opposit'ely extending annular flange-.-y surrounding the opening inthe web yto provide upperand lower, valve seats 1l andf12 respectively.

The valve seat 11 is adapted to be engaged byV a manually operated valve4for shutting'Af oii1 the flow of the heating medium through 75 thevalve casing, this valve comprising a valve stem 13 threaded through abushing 14 `mounted in the upper end of the valve casing 5 and operatedby the handle 15. "The lower,

end of thelvalve stem 13 has a swivel connec- 80 tion 16 with a valve 17that is constructed as illustrated with afre'movable and renewable discmember or Y'washer tov compensate for wear.

annulus 18 castintegral with the fitting 9V and surrounding the same, atubular cross 90 web 19 extending bet-Ween opposite sides of ring orannulusas illustratedV with the intermediateportion of thetubular webtraversy ing the fitting 9l to be disposed in the path of/ kflow of theheat-ing medium so that expansible fluidwithin theannulus and web isrendered more sensitive to varying heat` conditions. Thering or annulusis charged with/expansibleluid by means of tubularnipples thatua(l areclosed by screw plugs 20.

The thermostatically operated valve thatV open end soldered, welded orotherwise secured to the walls of the web opening to place theeXpansible tube in communication with the web and annulus. Acylindrical. plug core 22 is disposed within the eXpansible tube 21 withthe upper end thereof anchored to the closed upper end fof theexpansible tube, while the lower end of the plug core extends downwardlythrough the opening in the.

upper wall of the web 19, the plug core moving in wiping contact withthe wall of the lweb opening, the core having a longitudinally extendingfacial' groove 23 to permit the Viiow of expansible luid from' theannuhis n and web into the eXpansible tube 21. A valve 24 is carried bythe upper end ofthe eXpansible tube 21 and is adapted to be moved intoengagement with the valve seat 12, and to eliminate vibration of. thevalve 24Vand to insure proper operation` of the'therinostatic i devicesassociated therewith, .there is provided a coil spring 25 interposedbetween the Vvalves 17 and 24. i

From the above detailed description of the device, it is believedv thatthe construction and operation thereof would at once be'apparent, vitbeing noted that the flow of heating medium through the valve casing maybe shut off when desired bythe manually operated valve 17 that isengageable with the valve seat 11. 'I he automaticy closing oi the valveis accomplished by the thermostat-ically operated valve 24 that movesinto engagement with the seat.12, the atmosphere or air surrounding theradiator valve lowing in l 'Contact with all surfaces/of the ring orannulus 18 while theheating medium flows in Contact with the web 19 torender the operation of the thermostatic devices more sensitive. TheeXpansible fluid .causing eXpansion andcontractionof the expansible tube21 and coriespondingmovement of the valve 24: toward and away from itslseat 12.

A I/Vhile there is herein shown and described the preferred embodimentof the invention, it is to be understood that minor changes may be madetherein,

in the scope of the invention as claimed;

What I claim as new is: y f j 1. In an automatic thermostatic radiatorvalve, valve casing,a doublevalve seat therein, and manual andtlierinostatically operatsuch as will fall with- Y `extending betweensides of the annulus and transversing the valve casing in the path offlow of the heating medium.

3. In an automatic thermostatic radiator valve, valve casing, a doublevalve seat therein, and manual and thermostatically operated valvesrespectively engaged with the valveV seats, thetherinostatic valvecomprising anexpansible iiuid containing annulus formed integral/withthe valve casing and surrounding the casing, and an expansible tube incommunication with the annulus and carrying vrthe thermostaticallyoperated e valve` and aftubulaijweb extending between sides of theannulus'and transversing them valve 'casing in the path of flow of theheating medium. 1 p

"In testimony whereof I affix my signature.
